FERRULE FOR PIPE-JOINTS.

SPECIFIATION forming part of Letters PatentV No. 278,061, dated May 22, 1883.

Application filed September 29, 1885.. (No model.)

To all whom it may concern Be it known that I, JOHN F. SULLIVAN, of Brooklyn, Kings county, in the State of New York, have invented certain new and useful Nimportant, for several reasons, to make the ferrule of some ot' the alloys generally denominated brass It is common to make them of cast-brass, which necessitates the employ: ment of a large quantity of that expensive material. drawn tubes of brass for such ferrules; but the enlargement of each having been heretofore made in a plain ange'sufticient strength was not offered to endure the calking and the subsequent strains to which thejont is liable to vbe exposed. I have discovered and practically Wrought out a construction which allows the use of relatively light tubes ot' drawn metal to effect a strong junction with the cast metal. `It is formed by spinning theV end of the ferrule, so as to form a`s1noothly -rounded ring. '.Ihe particles ot' metal in this form brace each other. The construction ot' the end is further fortified by inclosing a previouslyformed ring of wire of a size just sufficient to lill the ring of metal which is so spun as to inclose the wire. Thus equipped, the metal of the tube is further re-enforced and braced by the ring, which is thus reliably -engaged with it.

The accompanying drawings form a part of this specification, and representwhat I consider the best means of carrying out the invention.

Figure l is a longitudinal section, showing the invention as fully applied for use. Fig. 2 is a side elevation of the ferrule with its peculiarly-formed end alone.

`Similar letters ot reference indicate corresponding parts in both the figures. Y

A is the cast-iron pipe, and A an enlarged end forming the socket thereof.

Efforts have been 'made to employ end ot' the tube D is spun outward and over upon itself it completely embraces the wire ring E. The small space between the spun metal D and the wire E may be filled with solder G to still further increase the strength. For this purpose the wire E should be previously tinned, and the adjacent surface of the spun metal D touched with acid. I do not esteem soldering generally necessary.

The junction of my ferrule to the lead pipe may be made by abutting the end of the ferrule against the end of the lead pipe or by socketing the ferrule a distance more or less into the interior of the soft-metal pipe. rIhe joint may be secured by wiping, as above described', or by any other means. Such junction forms no part ot' my invention.

Vhen my ferrule. after being strongly and rigidly fixed to the lead pipe by any ordinary or suitable means, is inserted in the socket A and melted lead or solder poured in the joint `around it, the side ofthe spun vportion D which is deepest in thesocket A and farthest from the melted metal is preserved by the construction from attaining any injuriously high temperature. When the end ot the thin tube is simply flanged out, the heat of the melted metal employed for calking injures its qualities, and lnakesitstill morelikely to be straightened out or broken'oft1 when the oalking metal is subsequently driven home tightly by a calking-iron.

H is the calking-metal.

Modifications may be made in the forms and proportions. Parts ot' the invention can be used without the whole. My ferrule will serve with some success without the solder G and without the ring E. Instead ot' using drawn tubing, I can use brazed tubing. Instead of using brass, I can use iron tubing properly tinned; but I prefer drawn brass tubing.

B is a lea-d pipe; .0, a wiped joint of solder, l I claim as my invention- IOO l.
